The project “has a capacity of 700 megawatts, spans 575 kilometers and will strengthen Ireland’s energy security and renewable energy imports,” it said.
The cable will run in a south-easterly direction from Knockraha in County Cork, Ireland, past Britain’s Land’s End to reach France at La Martyre in Brittany.
As technology advances, similar buildings are becoming more and more common. The North Sea Link between Norway and Great Britain set a record last year as the longest electricity cable of its kind, 720 kilometers.
But bigger projects are underway. For the export of solar power from Morocco to Great Britain, a 3,800 kilometer long giant cable is being prepared, with a budget of SEK 230 billion. And between Australia and Singapore, a 5,000 kilometer long cable is planned, also intended for large amounts of solar energy.
The budget for the Franco-Irish construction is just over 1.6 billion euros (17.6 billion kroner). It is managed by Siemens Energy and France’s Nexans, and should be completed in 2026.
